AutoSync automatic OTA firmware update
Occasionally we add new features to the AutoSync or fix minor bugs/glitches that might occur in the
field. Updating the AutoSync is extremely and directly over WiFi, you do not need a PC/laptop.
Firmware updates usually occur automatically in the background whenever the vehicle is within range of
your home WiFi network and has been parked/ignition off for more than several minutes. However you
can also manually trigger a firmware update by going into the AutoSync Info page (main menu, page 3)
with the key on engine off
, and press “Firmware Update”.
NOTE: If you have purchased BCM tuning, the BCM tune files are only downloaded when you go into the
AutoSync Info page and manually trigger a firmware update. BCM tune files do NOT get automatically
downloaded when the AutoSync does the automatic firmware update mentioned above.
First, you must create an account on the BT DieselWorks AutoSync firmware update server. Scan the QR
code on the AutoSync with your phone and it will take you to the AutoSync registration page. If you are
registering via a computer, go to autosync.btdieselworks.com (do NOT forget to enter your AutoSync
serial number if doing manual registration via a computer)
NOTE: Be sure that your truck is parked within range of your WiFi router, or inside a garage with WiFi
access. Leaving the vehicles doors/windows OPEN might be needed to ensure that the AutoSync can
pick up a good WiFi signal. If the update procedure fails, or “hangs” more than 3-4 times, the WiFi
signal is probably too weak, and you must use the “offboard” procedure explained on page 19.
NOTE: If your truck has an active OnStar 4G internet WiFi hotspot plan active, the AutoSync can be
configured to automatically connect to your trucks WiFi hotspot to handle the firmware update.
- Ignition is ON, engine OFF. Access the AutoSync menu (press the cruise CANCEL button) and scroll to
PAGE-4. Press “AutoSync Info”.
- NOTE: The following steps must happen within ~60 seconds, otherwise the AutoSync will time out,
exit the setup menu, and you will have to start over again.
- NOTE: If your truck has an active WiFi hotspot internet plan, skip steps 2-5!
